Question

tolong jawab y kak nanti ​

Answer 1

Jawaban:

1. kubus mempunyai 12 rusuk

2. 8 titik sudut

3. nomor 2

4. V kubus = s × s × s

= 15 × 15 × 15

= 3.375

5. 14 dm³

6. V kubus sisi 26 = s³

= 26³

= 17.576

V kubus sisi 30 = s³

= 30³

= 27.000

selisih kubus ll - l

= 27.000 - 17.576

= 9.424 cm³

7. V balok = 1/2 × V kubus

= 1/2 × 26³

= 1/2 × 17.576

= 8.788 dm³

8. V balok = p × l × t

= 15 × 8 × 4

= 480 cm³
